The improvement consists inmaking a groove on one side of the nail and near the point, so that whenthe nail is driven onto an iron-plated last, or a born or other hardresistingsurt'ace, the point will bend toward the grooved side and forma clinch; also, in the shape of the points, the opposite sides of whichI m-tke symmetrical in form to keep the nail from running or drawing ina slanting direction, and in tapering the point on all four of thesides.
